It is recorded in Sunan Abi Dawud and in Sunan Imam Tirmithi and other books of hadith that Rasulullah (sallallahu `alayhi wasallam once said to his uncle Hadrat `Abbas (r.a.) : O Abbas!O my uncle! Shall I not give you a gift? Shall I not show you something by means of which Allah Ta`ala will forgive your sins, the first and the last of them, the past and recent, the unintentional and the intentional, the small and huge, the secret and open?

Rasulullah (sallallahu `alayhi wasallam) then taught him the Salah al-Tasbih. Furthermore he advised him that it be offered daily, if possible. If not then every Friday or once a month or once a year or at least once in one’s life time.

Salah al-Tasbih consists of 4 raka`at. It can be performed any time of the day or night except at the makruh times.

The following tasbih is recited seventy-five times in each rak`ah totalling 300 in the 4 raka`at.
